We used this BLIKA railing system to swap out our outdated stairs and are incredibly happy at the outcome. The kit has high-quality mounting hardware for the subfloor (wood or concrete), and we added a wood handrail with black 1/8 inch black cable wire. My husband did the install using the included instructions and online visual instillation help, but just a heads up, you WILL need these specific items to finish the job: a pneumatic crimper, 5/16" ID Black Angle Washers for Cable Railing Stair Ends, and the Stainless Steel 30 Degree Black Angle Beveled Washer for 1/8", 3/16" Cable Railing Hardware. You also need the Cable Railing Angled Washer for the posts.
